Pros Both the audio quality and the appearance is excellent. Most bluetooth headphones look gaudy. This one is very sleek & discreet. To me, it looks more stylish, futuristic than the phones in Minority Report.
Cons The ear buds are made of some type of material that gets... gooey over time (No, it's not ear wax.) which is pretty gross. Then too, my battery died after about 6 months. I left it off the charger for a week and it never recovered. Pretty poor.
Summary I have owned several different model Plantronics headsets over the years, and all have had exceptional sound quality -- and all have experienced some kind of problem. It's almost if their design dept is on the ball but their manufacturing arm needs replacing. I have contacted them about both headsets/problems and they were less than responsive in both instances. Bottom line: their products are great, but don't get used to it.
Pros Good car noise supression.
Cons Low Battery Life
Summary I bought a Plantronics Discovery 650E headset and liked it. A few days later I ran across a discovery 665 with Audio IQ. I decided to buy it as well to do a test to see if it was worth the extra money. I made calls from my vehicle, which is very loud from road noise. I found the 665 does have a lot less background noise than the 650. The two headsets look identical, but sound very different. My voice was clear using the 650, but the background noise was heavy. I also tested the 665 with the air on full blast. The 665's sound quality did degrade, and I suspect this will be the case in high winds. Most phones can't conquer wind noise either.
My 665 came with the USB, Car, and AC chargers. I guess Plantronics decided we require AC chargers.
I would definitely reccomend the 665 over the 650E for sound quailty. Plantronics got it right with this series of Bluetooth headsets. Finally a Bluetooth headset that can be used easily without wearing it all the time.
Pros sound quality, charging options
Cons earbud security. Lousy and breakable earloop
Summary Got this to replace the Jawbone 2 I gave a test to previously. The packaging claimed noise cancellation and sound enhancement with "AudioIQ". Fair enough.. sounds promising.
Paired perfectly with my LG VX8600. First and foremost, the sound quality, both sent and received, was very good. Had a more "bassy" sound the other earpieces I've tried which sometimes caused words to be misunderstood, but overall, I was pleased with the sound quality.
Using it in a car with the windows up, stereo off and just the vent blowing on medium, is where it failed. The listener said the background (engine) noise was sometimes overwhelming my voice. When I paused at a red light, the problem went away. This is similar to other previous headsets that don't have noise cancellation... so this made the headset kind of useless for me in a car.
Lastly, I found all the earbuds uncomfortable and not secure. The unit kept wanting to fall out of my ear. The way the earbuds attached made me feel that over time of twisting it into my ear, it'd eventually break off. The included earloop was a necessity, and definitely helped, but it was flimsy and attached with a wire loop. Again, longevity of this was in doubt.
I ultimately returned the unit, since I wanted something with real noise cancelling to help make me more audible while in a car. Also, because I just couldn't get comfortable with the earbuds. That latter issue is subjective to the wearer, of course. Otherwise, this unit had good sound quality and reasonable range.
Pros Lightweight, nice charging options
Cons Cheap design, not durable; low audio
Summary For the record, I bought this headset at retail and spent what was basically the full MSRP.
My requirements were fairly simple:
Lightweight and comfortable.
The ability to mute from the headset.
Good battery life.
Anything above and beyond would be considered a bonus.
As it turns out, this headset failed on 3 of the 4 criteria for me.
While the headset is unquestionably light and the gel buds fit nicely, the cheap construction of the plastic that connects the exchangable earbud to the headset itself means that you will eventually end up with a loose fit on your ear.
If you're like me, a person who handles the unit quite a bit in the course of a typical day, you will end up losing the earbuds, as they easily get knocked off as the connector piece progressive loosens (we're talking only a few weeks after purchase). At this point, I have lost all three of the included earbuds!
You can mute a call from the headset but, it requires that you press the volume up and down buttons simultaneously. Well, one of the buttons broke off (not sure when and how) so it is now not only impossible to mute, but to adjust the volume up.
I exagerated that last point a bit, as I was able to stick an eyeglass kit screwdriver in the hole where the button used to be and raise the volume to the max setting. However, even at max, the volume is not loud enough to be used in the car (unless all windows are closed and radio is silent) or on a busy city street without constantly asking the caller to repeat themsleves.
I've only been able to run the battery dead on two occasions that I can recall, so that's not bad in my book. I just wish the rest of the unit performed as well.
Bottom line...it had a lot of potential to be a solid unit, but poor construction prevents me from recommending this headset.
Pros Compact, Light, Easy Fit, Excellent Sound
Cons Poor Battery Life, Earpiece Flimsy, Price
Summary I've owned my Plantronics 665 for about 9 months. In that time, I've really come to loathe this product.
The earpiece pops out way too easily. More than once it's popped out and I've had to scour the floor looking for the earpiece. This last week I lost my last good earpiece and had to re-order through ebay..bestbuy and my other area electronic suppliers do not carry replacement ear buds.
The batterly life is dismal at best. If you're a PS3 owner as I am, this is not a very good headset alternative as the battery life is a few hours at best, not ideal for a marthon session of COD4.
On the bright side, the sound is excellent and those taking my calls say my voice comes through loud and clear; no crackling, breakup, or noise.
The earpiece does not like my walking away from my phone..I get about 10 feet and it starts to beep. In addition, it's also a bit finicky when my phone is my pants pocket...will disconnect sometimes. So, I've been forced to either keep it my coat pocket or on my belt.
For the money I paid (100.00), I'm really disspointed in this product.
